That seems high. We flew Christmas week.....absolute peak dates.....from Buffalo (to Orlando on December 23rd and home to Buffalo on December 30th) for an overall cost of $1125 for three of us ($375 pp). We thought that was pricey compared to other times of year.
Both flights were non-stop. One way via Airtran, the second via Jetblue. And that included our baggage (one free bag per person on Jetblue, and checking one bag PP on Airtran) as well as Airtran seat selection fees.
Our flights last August from Syracuse, NY were $868 for three of us ($290 pp). Flights this year were cheaper on our dates from Syracuse than Buffalo, and we paid $330 pp round trip (again, all flights non-stop). Each of these are Jetblue flights so there were no additional charges for baggage, seat selection, etc. to factor in.
